“…Flow meters of different designs were developed to measure flow rates of liquid metals. Methodologies and a technique were developed later for measuring electromagnetically the liquid metal local flow rate (velocity) vectors in channels and fuel rod bundles, and measuring the coolant mixing characteristics in experiments in air with a small fraction of gaseous tracers added in the form of Freon or propane (Rachkov et al 2018, Sorokin et al 2021b.…”

“…Most attention has been given to thermohydraulic studies for the most heated and essential component of a reactor plant (the reactor core) affected, in the course of life, by a number of factors, including design, mode, process, radiation and operating factors (Rachkov et al 2018). It was shown that there was no thermal (contact) resistance at the coolant -heat-exchange surface interface when the concentration of impurities in the coolant did not exceed their solubility at the circulating metal temperatures.…”

“…Для измерения расходов жидких металлов со зданы расходомеры различных конструкций. Позднее были созданы методики и техни ка электромагнитного измерения векторов локальных расходов (скоростей) жидкого металла в каналах и пучках стержней, измерений характеристик перемешивания тепло носителей в опытах на воздухе с добавкой малой доли газообразных трассеров в виде фреона или пропана [5,6].…”

“…Наибольшее внимание уделено теплогидравлическим исследованиям самого высо конапряженного и ответственного узла реакторной установки -активной зоны реакто ра, подвергающегося воздействию различных факторов: конструктивных, режимных, технологических, радиационных и эксплуатационных в процессе кампании [6]. Было показано, что на границе раздела теплоноситель поверхность теплообмена термичес кое (контактное) сопротивление отсутствует, когда концентрация примесей в теплоно сителе не превышает их растворимость при температурах циркулирующего металла.…”
